What makes power feed better then standard feed?
With standard feed the balls are all stacked inline from the elbow to the chamber. After the gun is fired, blowback pushes on the ball that is going to feed next and this blowback pushes on all of balls up to the hopper. This can cause chops in rapid fire because the balls are pushed away from the chamber and eventually a ball will only drop half way into the chamber when the gun is fired, thus causing a chop. The power feed puts a 90 degree bend in the feeding of the balls so that the blowback only pushes on the next ball inline and not the rest of the balls behind it. There is little room for the next ball inline to move from the blowback, therefore it stays in the same position and drops into the chamber at the right time.
